1) No, that style is more like a 3D, and I do 2D... Plus, your references are quite poor quality model up there. So, if you need something like it - I'm not your guy... Sadly.
2) Im educated and adaptable; all you have seen is in my portfolio (already shown) 50% of other styles.
3) Well, recently I've finished a room with 5 upgradable items (props). It is just a bedroom, but... Im strongest at characters. BG, props, color, and other stuff serve as my instruments to talk through my lines. In short, I'd say: sprites and concepts. But I can also help with UX\UX and overall game design. Have exp in that... Made a VN, Localisation with text, voice-over, textures, and all that.
4) Ofc I will be comfortable with a small test, even with a few coins to complete.
5) Well, my rates can't be described easily. Because I need a lot of info before charging someone. A man has to eat; it's for sure. But if you need some numbers... Usually I take 30$ for a simple raw job (low money, low time, low effort, but my skills, education, and experience); 100$ for a character concept (black and white, front view, back view, side view, 3 expressions, 3 items, short story) and 200 for a colored one; environments start from 25$.... Ect... Overall, the more quality and detail you want, the more I charge. One background with color and all can be made for 25$ but a decent one will cost at least 150. 25 is made like in 1-2 days max, and a good one 3-7...
6) Oh yeah! Im interested in long jobs. I hate irresponsible people, and I've been searching for a way to work with JP for a while now... I think you have much more discipline in you, but it might sound a bit... Too much love for Japan. Ha-ha.
7) I would prefer another project, honestly. I'm not sure your ideas (as im aware from your description) are capable to bring bit money to the table... But I believe in people and their bright ideas. So, mostly I'm into your project as a portfolio piece; you're the first Japanese I've met here and.... Well, I think I could find something interesting in this one when I know about the plot, setting, and all that.
